Abstract
Appareil permettant de refendre une bande continue d'une nappe de matière thermoplastique comprenant un tambour rotatif supportant la nappe passant sur sa surface et un couteau dont le tranchant est reçu dans une gorge circonférentielle du tambour et qui est chauffé à une température d'environ 90 à 150 degrés C inférieure à la température de fusion de la nappe. En chauffant le couteau, on réduit sensiblement la force de coupe qu'il faut exercer.
